Abstract (en)
[origin: WO9006962A1] This invention relates to a new modified silicate composition prepared by the reaction of an alkyl silicate or its oligomer with a specified active hydrogen compound in a specified ratio and to a method of producing a sand mold therefrom. More particularly the invention relates to an improvement in the production of a sand mold by using an organic binder and a hardener therefor, and a ceramic binder and a hardener therefor to produce economically a mold having an excellent strength without resort to complicated procedures.
